Best WooCommerce PDF Invoice Plugins Compared for 2026

Choosing the best WooCommerce PDF invoice plugin depends on what happens after an order reaches your store.

If you only need automated PDF invoices, a focused invoicing plugin may be enough. But stores that also manage packing, shipping, refunds, tax documentation, or electronic invoicing need a broader workflow.

For stores that want invoicing and fulfillment documents managed from one place, WowInvoice is our top pick. WP Overnight stands out for its mature invoicing and e-invoicing ecosystem, while WebToffee offers a broad modular document suite. YITH, Challan, Flexible PDF Invoices, and Print Invoice & Delivery Notes each suit more specific requirements.

This comparison looks beyond feature count to identify which WooCommerce invoice plugin makes the most sense for each workflow.

How We Evaluated the Best WooCommerce Invoice Plugins

We compared the plugins around the parts of an invoice workflow that can materially affect a WooCommerce store:

  • Invoice generation and automation
  • Invoice numbering and management
  • PDF and template customization
  • Additional order documents
  • Tax, VAT, and e-invoicing capabilities
  • Customer and admin workflows
  • Integrations and compatibility
  • Pricing model and overall value
  • Ease of setup and day-to-day use where we had direct experience

For features, current capabilities, and product boundaries across all seven plugins, we therefore prioritized official product pages, documentation, WordPress.org listings, and current vendor information.

7 Best WooCommerce PDF Invoice Plugins

1. WowInvoice

Best for: WooCommerce stores that need one automated solution for PDF invoices, packing slips, delivery notes, and VAT-related documentation.

WowInvoice centralizes WooCommerce invoices and fulfillment documents in one document-management workflow, with automated generation, flexible customization, and support for EU VAT documentation.

Its six primary document workflows include:

  • PDF invoices
  • Packing slips
  • Picklists
  • Shipping labels
  • Delivery notes
  • Credit notes

UBL invoices are also available as an additional machine-readable e-invoicing option.

Key capabilities:

  • Generate documents automatically based on WooCommerce order status
  • Attach invoices and other documents to order emails
  • Let customers download documents from their accounts
  • Customize numbering, branding, product tables, and tax information
  • Add barcodes, QR codes, and RTL support
  • Manage documents in bulk

Ease of use: In our hands-on use, WowInvoice has one of the clearest document workflows. 

All document types are accessible from a central dashboard, and each follows a similar configuration and customization process. Shared store information also carries across documents, reducing repetitive setup.

EU VAT support: WowInvoice can collect and display EU VAT/Tax IDs on invoices and credit notes using its checkout field, supported third-party plugins, or order metadata. 

It does not perform live VIES validation itself, so stores requiring VAT-number validation need a compatible validation plugin.

Main trade-off: WowInvoice is newer than established alternatives such as WP Overnight, so stores prioritizing the longest public track record may prefer a more mature ecosystem.

2. PDF Invoices & Packing Slips by WP Overnight

WP Overnight’s PDF Invoices & Packing Slips for WooCommerce is one of the most established plugins in this comparison, with more than 300,000 active installations and over 1,800 WordPress.org reviews.

Screenshot of WP Overnight plugin

Key capabilities:

  • Automatically generate PDF or XML invoices
  • Attach invoices to selected WooCommerce emails
  • Generate packing slips
  • Bulk-generate documents
  • Customize invoice templates
  • Support customer invoice access

Its biggest differentiator is structured e-invoicing support, including:

  • UBL 2.1
  • Peppol BIS 3.0
  • CII D16B
  • Factur-X
  • Multiple ZUGFeRD formats

The Professional extension adds:

  • Credit notes
  • Proforma invoices
  • Receipts
  • Advanced bulk exports
  • Separate numbering
  • Multilingual workflows
  • Automatic storage through Google Drive, Dropbox, FTP, or SFTP

Ease of use: WP Overnight is the strongest competitor to WowInvoice in usability. Its interface is relatively structured compared with several older invoice plugins.

Main trade-off: The extension-based architecture is flexible, but stores wanting invoices and fulfillment documents inside one consolidated workflow may find it more fragmented than WowInvoice.

3. WebToffee 

WebToffee treats invoicing as part of a wider WooCommerce order-document ecosystem rather than as a standalone invoice feature.

Its core invoice solution supports:

  • Automated PDF invoices
  • Packing slips
  • Credit notes
  • Email attachments
  • Customer downloads
  • Custom invoice numbering
  • Bulk document exports
  • VAT, GST, and other tax information
  • UBL/XML electronic invoices

Its broader ecosystem adds separate solutions for:

  • Shipping labels
  • Dispatch labels
  • Delivery notes
  • Address labels
  • Proforma invoices
  • Picklists
  • Advanced document customization

This modular approach works well for stores that expect their document requirements to grow. You can begin with invoicing and add fulfillment or customization tools as needed.

Main trade-off: WebToffee offers considerable breadth, but advanced workflows may require multiple plugins or a bundled suite rather than one unified plugin.

4. YITH WooCommerce PDF Invoices & Packing Slips

YITH is strongest for stores that need deeper control over invoice administration and document design rather than a large warehouse-document system.

Key capabilities:

  • Automatic or manual invoice generation
  • Sequential numbering
  • Bulk invoice management
  • Customer downloads
  • Proforma invoices
  • Credit notes
  • Packing slips
  • Google Drive and Dropbox backups

Customization is a major strength. YITH provides:

  • Nine ready-to-use templates
  • A Gutenberg-based template builder
  • Multiple invoice templates
  • Control over text, images, colors, styling, and layout

For tax-related workflows, YITH can collect VAT or SSN information during checkout and display it on documents. It also supports XML-based electronic invoicing for Italian businesses.

YITH integrates with other products in its WooCommerce ecosystem, although some integrations require separate premium plugins.

Main trade-off: YITH offers strong invoice and template management, but stores that need picklists, shipping labels, and a broader fulfillment-document workflow may find WowInvoice or WebToffee better aligned.

5. Challan – PDF Invoice & Packing Slip by WebAppick

Challan combines core WooCommerce invoice automation with strong multilingual and region-specific functionality.

Key capabilities:

  • Automatic PDF invoice generation and email attachment
  • Packing slips, shipping labels, delivery notes, credit notes, and proforma invoices
  • Customer and bulk invoice downloads
  • Custom invoice numbering, branding, fields, and product details
  • Digital signatures, barcodes, and QR codes
  • RTL support and multilingual fonts
  • Dropbox document storage
  • GST-oriented invoicing for India
  • ZATCA e-invoicing support for Saudi Arabia
  • VAT and tax information support

Ease of use: Challan provides extensive configuration but feels more settings-heavy than WowInvoice. Its workflow follows a more traditional settings-based approach.

Main trade-off: Challan is feature-rich, particularly for regional requirements, but merchants wanting a simpler visual document workflow may face a steeper learning curve.

6. Flexible PDF Invoices for WooCommerce by WP Desk

Flexible PDF Invoices stands apart because invoices can be created directly inside WordPress, even when they are not connected to a WooCommerce order.

Key capabilities:

  • Manual and automatic invoice generation
  • Custom invoice numbering
  • Proforma and correction invoices
  • Tax rates and payment methods
  • Bulk invoice downloads
  • EU VAT-number fields
  • VIES VAT-number validation
  • OSS/MOSS support
  • Reverse-charge workflows
  • VAT currency conversion
  • Reports and Gutenberg-based invoice templates

This makes it particularly suitable for stores where EU VAT handling and invoice administration matter more than pick-pack-ship documentation.

This is an important distinction from WowInvoice: WowInvoice can collect and display EU VAT numbers and work with external validation plugins, while Flexible Invoices Pro includes VIES validation within its own EU-focused workflow.

Main trade-off: Flexible PDF Invoices is strong for EU VAT and accounting requirements, but it is less suitable for stores wanting invoices, picklists, packing slips, shipping labels, and delivery documents managed as one fulfillment system.

7. Print Invoices & Delivery Notes by Tyche Softwares

Print Invoice & Delivery Notes for WooCommerce suits stores that need practical PDF order documents without a large document-management ecosystem.

Supported documents include:

  • Invoices
  • Delivery notes
  • Receipts
  • Credit notes
  • Packing slips

Key capabilities:

  • Generate documents individually or in bulk
  • Let customers access invoices from their accounts
  • Customize branding and document fields
  • Adjust typography, colors, numbering, and layouts
  • Generate and store PDF documents

The plugin has changed significantly in 2026. Recent releases introduced:

  • A rebuilt React-based admin interface
  • PDF generation and storage
  • Sequential invoice numbering
  • Dedicated templates
  • Expanded customization options

It currently has more than 30,000 active WordPress installations and remains available free through WordPress.org.

Main trade-off: Its strength is conventional PDF documents and printing. Stores needing structured e-invoicing, advanced EU VAT validation, or a wider pick-pack-ship workflow should consider more specialized alternatives.

Which WooCommerce Invoice Plugin Should You Choose?

There is no useful universal answer unless we first define what the store actually needs.

If your priority is…Plugin to consider
One plugin for invoices plus fulfillment documentsWowInvoice
A mature invoice plugin with extensive e-invoicing formatsWP Overnight
A modular ecosystem covering many WooCommerce order documentsWebToffee
Detailed invoice management and visual template buildingYITH WooCommerce PDF Invoices & Packing Slips
Multilingual and region-specific invoice workflowsChallan
EU VAT validation and accounting-focused invoice managementFlexible PDF Invoices
Straightforward PDF documents and bulk printingPrint Invoice & Delivery Notes

For most stores, the first decision should be whether you need an invoice plugin or an order-document workflow.

👉 If invoices and packing slips are the main requirements and mature electronic invoice standards matter, WP Overnight is difficult to ignore.

👉 If you expect to assemble a larger document stack from specialized components, WebToffee gives you considerable room to expand.

👉 If EU accounting processes such as VIES validation and OSS/MOSS are central to the business, Flexible PDF Invoices deserves more attention than its sixth-place position might suggest.

For stores that want invoice creation connected directly with picking, packing, shipping, delivery, and refunds, WowInvoice provides the most consolidated workflow among the plugins compared here. 

Its centralized document dashboard and consistent configuration model are also why it was the easiest option for us to navigate during deeper hands-on use.

Final Verdict

The best WooCommerce PDF invoice plugin should reduce work in the specific document workflow your store actually uses.

WowInvoice is our top overall choice for stores that want invoices and fulfillment documents managed together. 

It combines six primary document types in one system, adds UBL as an electronic invoice option, provides flexible document customization, and supports EU VAT/Tax ID documentation without requiring separate document plugins for each stage of the order process.

WP Overnight is the stronger choice if maturity and extensive structured e-invoicing formats are your priorities. WebToffee makes more sense when you want a modular document ecosystem, while YITH, Challan, Flexible PDF Invoices, and Print Invoice & Delivery Notes each become stronger choices for their respective specialized workflows.

Choose based on the documents, tax requirements, automation, and administrative workflow your store actually needs, rather than which plugin simply has the longest feature list.
